A few examples for you14 – Sheyi Ojo (£2million, MK Dons to Liverpool) Sheyi Ojo joined Liverpool so long ago that Kenny Dalglish was in the midst of his second spell as manager at Anfield in 2011 when the then-14-year-old signed. The Reds were forced into a bidding war with Chelsea for the winger, who had already won two England youth caps at international level before leaving MK Dons.

18 – Luke Shaw (£27m, Southampton to Manchester United) Edging out Wayne Rooney by £2m is close friend of Jose Mourinho, Luke Shaw. The 18-year-old had just been named in the PFA Team of the Year when Manchester United swooped in to sign him for just under £30m in summer 2014. He probably didn’t expect to be behind Matteo Darmian, Daley Blind and Henrikh Mkhitaryan in the left-back pecking order two-and-a-half years later.

29 – Zinedine Zidane (£46.7m, Juventus to Real Madrid) I know you didn’t ask for the difference between football 15 years ago and today to be defined in two transfers, but I’m going to do it anyway. In 2001, Zinedine Zidane cost £46.7m at the age of 29; he was the best player in the world. In 2016, Hulk cost £46.1m at the age of 29; he was not the best player in the world.

33 – Claudio Bravo (£17m, Barcelona to Manchester City) You can keep the faith that Bravo might turn around his Manchester City form, but let’s not pretend he was ever a long-term option. While Joe Hart stews in Turin, a 33-year-old Chilean does a working impression of when you made your little brother go in goal in the garden for a wonderful football ego trip.
